So currently I can't use stream after its connection closure? I thought the api would reliably return some kind of error code.

Well, once I finish this PR (ETA: this week) then it won't matter, but the problem before was that the connection would be deleted when you close the stream, so any access would be a use-after-free, without adding more state to the stream itself.
